This invention relates to devices for dehorning animals, and the primaryobj ect of this invention is to provide an improved Vdehorning saw thatmay be readily supported from the neck of the animal to be dehorned. Astill further object of the invention is to provide a dehorning sawwhich is comparatively simple in construction, and which in# cludessupporting means therefor adjustable for accommodating the neck ofvarious sized animals. 7

A still further object of the invention is to provide a dehorning sawwhich maybe read-V ily mounted on the neck of various sized animals andwhich can be manually operated with facility. y A p Other objects andadvantagesof the inven tion will become apparent during a study of thefollowing description taken in connec- 2 .0 tion with the accompanyingwherein:

Figure 1 is a side elevational view showing the device as applied to ananimal,

Figure 2 is a. vertical sectional view there# Figure 3 1s a fragmentaryend elevational view thereof, Y Figure 4 is atop plan view of the sawand associated mechanism,

Figure 5 is a detail sectional view taken substantially on the line 5 5of Figure 4.

Figure 6 is a fragmentary detail view partly in section and partly inelevation illustrating certain details of construction to be hereinaftermore fully referred to.

'Vith reference lmore in detail to the drawings, it will be seen that Iprovide a body member including a pair of spaced upper and lower plates5 and 6 respectively. The plates 5 and 6 are retained in spacedassembled relation throughthe medium of vertical bars 7 thatl areconnected together through the medium ofpa pair of spaced transversecross bars 8. Movable relative to the body member, and supported on thelower plate 6 isa horn engaging member 9 that is provided..

with a Vlongitudinally extending slot 10. The

slot 10 at the forward end ofthe member" Yy 9 is suitably shaped as at11 to accommodate drawings and engage the `horns of `the animalv ,l

dehornedq, y i A. y,

Adjacent theopposite end of 'thefslot,jand on opposite side edges oftheslot, the plate is provided with rack teethly12g Meshing with the teeth12 for imparting lthe Sliding movef4 ment to the member 9 relative tothe plate 6 is l a worm 13. The plateV lis provided with 'a'V suitableopening 14 registering with the slot 10 and accommodating the worm 13.The worm 13 is mounted on asuitable shaft journalled in suitablebearings 15, o ne'beneath the lower edge of each cross memberS. Alsomounted on the shaft is a suitable gear wheel 16 that meshes with a gearwheel 17 is mounte 'on the lower end of a vertical shaft suitablyjournalled in bear! i i ings 18 and 19 on the upper and lower plates' 5and 6. The upper end of the, shaft` is .Q equipped with al suitableactuating handle 2O. Obviously by rotatingthe handle Q0, rotativemotion, is transmitted to the worm 13 through the gearing justdescribed, and the worm 13 `meshing"withthe teeth 12: will y move thehorn engaging member 9 relative'to 7 theplate.V i A saw supporting shaft21 is suitably mounted in a verticalV position at the forward, end ofthe plates 5 and 6. Supported on the` ,o saw supporting shaft 21 is asuitable dislrf 50' cutter or dehorning saw 22that is adapted' to rotatein a horizontal plana Mounted on the shaft 21 adjacent the upper-end ofthe. shaft is a'pinion 23 that is adapted to'rotate in a horizontalplane. The pinion 23 meshesV 85' with arelativelylarge gear wheel 24that is splined to the s aft supporting the gear 17, andthe gear 24 alsorotates in a horizontal From the'foregoing then it will b seen 9'01 lthat when the end 11 receives therein thehhorn of the animal to bedehorned, byro tating the handle member 20 in thel proper direction, thevbody member including Vthe plates 5V andpv6` will move toward the ,lright 95 p ear wheel 17. The (f5 Figures 4 and 5, and hereinbeforedescribed rin detail, in suitable dehorning position on the animal, Iprovidera suitable yoke that includes a member that is adapted to extendtransversely of the neck of the animal,

and to the ends of which are pivoted as at 26 the uppercurved end ofside members 27 that are adapted to extend.l downwardly along oppositesides of the'animal. Bolted to the curved-upper end ofone of the sidemembers 27 as at'28 is theflower end of a suitably shaped bracket 29that has at its upper end a rest or supporting plate 30 pro-` vided withupstanding flanges or sides Y 31. The rest or plate 30 providesasupport; for slidably supporting the body that includes v the plates 5and 6, the lower plater6y resting kon the rest 30. Hinged to the upperedge of each of .the side members 31 is a retaining member 32 thatisadaptedlto overlie and engage the upper plate 5.V For retaining theformed on the side member 3l, andthe op- Vvous sized necks, each ,of theside members 27 has disposed in spaced relation thereto posite endthereof adapted tov be received yinlthe opening of a suitable lug 35formed onY the member 32 (see Figure'3). 'y Foraccommodating the neckyoke to varian adjusting plate 36 that is `adapted to be moved relativeto the sidey member 27-for contact with the adjacent side of the animal.

'- Each of the members 36 has a plurality of ratchet members 37 pi'votedthereto as at 38.

The member 27 is provided with a plurality of openings for accommodatingthe ratchet members 37,' and the 'upper edges of ythe openings 39 aresuitably beveled .to engage 40 obviously urge the teethof the rackmembers 37 into engagement with the beveled V es,

the teeth of the ratchet members 37 `or retainingl the sidemember 27 andits inember 36 in spaced relation relative to one another and at anydesired point of adjustment. y

' To each of the members 36 there are pivotedpreferably four of suchratchet members 37, two of which are arranged in vertical spacedalinement, and the remaining two'arranged in horizontal spacedalinement7 and the outer ends of the rack members 37 are all connectedtogether, one with the other through the medium of suitablesprings 40 asclearly rsuggested in Figure l. The springs edges of the respectiveopenings 39 (see Figure 6). For detachably connecting the lowerl ends ofthe side members 27 there is provided a suitable member 4l that ispivotallyconnected to the `lower endof one of the side members-27 as at42. The, member 41 is adapted vto extend under the neckof the animal.Aandwhas its freef'end' adapted to be lhingedly connectedylongitudinally twistedv side straps 44 that extend downwardly along thesides of the animal. Adjustably connectedto the lower end of each of theside mem- -bers 44'is a retaining strap 45 that is twistedlongitudinally adjacent its lower end to provide an inwardly andrearwardly directed end portion 46 that is adapted to extend underneaththe body of the animal on the inner; sides of the fore legs of theanimal. j

Each oiE the straps 45 adjacent its upper en d is provided with'alateral flange 47. Thev flange 47 is suitably apertured to accommodate abolt 48 that extends therethrough and@ also extends through averticalslot Vformed'V in the vertically disposed Iiange 49 formed on anadjacent side strap 44. will of vcourse have a suitable nut associatedVtherewith so that by tightening the nut, the side straps 44 and member45 may be re- The bolt 48 Y i' tained in longitudinal adjusted positionrelative to one another. Y

:The boltsv48 provide pivots for theinnerV ends of armsO. Each ofthearms 50 comprises a pair of longitudinally adjustable sections 51 and 52respectively, the ysection 51 being pivoted through the medium oftheboltY 48. The section 5l at its free end isprovided with'alongitudinally extending slot 53 that at its upper edge is suitablyserrated or otherwise formed to provide teethwith which is 'engaged apin or bolt 54 carried by the section 52 and operable in the slot 53 formaintaining the sections 5l and 52 in a predetei-, mined longitudinallyadj usted position.

At its inner end, the section `52 is provided with a suitablelongitudinally extending stop iiange 55 for contacting the upper edgeofsection 51 to retain thesections against pivotal movement with respectto one another in one direction. The section 52 A 'may also be equippedwith -a suitable-handle 56 to facilitate manual adjustment of thesections.

The section 52 of the respective arms 50 has. a pin and slot connection574 with one of the side members 27 which will permit the.V arms 50 toattain the angular position suggested in Figure l when the device isassembled onthe animal. The sections 5230i the respective arms 50 at theouter free'ends of the sections 52 are respectivelyequippedy with a jawengaging and'supporting head 58- that is adapted to engage the j aw ofthe animal rearwardly of the ears of the animal.

Links 59 are pivoted at one end to the side straps 59 may be formed ofmetal or any other suitable material for bracing the yoke 27 assuggested in Figure l.
